           Summary: Scaled down images in KOffice documents are extremely
                    blurry

        OS/Version: Linux
            Status: UNCONFIRMED

        AssignedTo: koffice kde org
        ReportedBy: takken phys uu nl


Version:           1.3 (using KDE KDE 3.2.0)
Installed from:    Compiled From Sources
OS:          Linux

Scaled down images in KOffice documents are extremely blurry. This is especially well visible when using images of scanned text, or screenshots. A more precise algorithm is needed.

Also, it looks like the scaling of images is re-applied every time the image needs to be re-drawn on the screen. A scaled version of the image should be created and cached when the image is inserted into the document. The scaled version only needs to be re-calculated when the image is resized, or the user zooms in on the document. Ideally, these calculations should be done in a seperate thread.
